Please be advised that on 11th September 2019 the President of the Lawyers Committee for 911 Inquiry (LCfor911Inquiry) held a press conference at the National Press Club in Washington DC in which he advised that the Lawyers Committee had lodged with the abovementioned court a petition requesting the court to order the US Attorney for the Southern District of New York to disclose whether or not he had empanelled a Grand Jury to receive and consider the evidence it had submitted in its petitions of 10th April 2018 and 30th July 2018 (a copy of the latter of which is available here:  https://www.lawyerscommitteefor9-11inquiry.org/lc-doj-first-amended-grand-jury-petition/) and , if not, to order the US Attorney to empanel such a Grand Jury.  On 7th November 2018 the US Attorney advised that he would comply with the law in respect of this petition but when asked in July 2019 if he had actually done so the US Attorney declined to say so due to the secrecy requirements of Grand Jury processes.

LCfor911Inquiry President Attorney David Meiswinkle’s address to the press conference may be viewed here:  https://www.lawyerscommitteefor9-11inquiry.org/.  In his press conference address Mr Meiswinkle expressed the legal opinion of the lawyers committee that the evidence of controlled demolition of the Twin Towers of the World Trade Center (WTC1 and 2) and of the Salomon Brother Building (WTC7) on 11th September 2001 by the use of explosives was ‘dispositive’, a legal term which he explained meant ‘beyond doubt’.

No formal membership, directorship, managerial or employment relationships held.  Occasional small donations made and occasional voluntary work undertaken.
This foreign principal is a section 501(c)3 non-taxable charitable organization under US law and is not classified as a "political organization" in the USA but maybe judged to be so under this scheme.
